BRUSH MECHANISM FOR CAN-WASHING MACHINES.

Patented Aug. 6,1918.

Application filed August 4, 1915. Serial 1v .-43,540. I

To all whom it may concern:

Be it known that I, ABRAM B. HERB, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Brush Mechanism'for Can-Washing Machines, of which the following is a; specification, reference being had therein to the accompanying drawing.

This invention relates to a brush mechanism for use in milk can washing machines, and moreparticularly to the machine described and claimed in my United States patent application, Serial No. 43539, filed Aug. 4., 1915.

The object of the present invention is to provide brush holding and operating mechanism, which shall be automatic in its action, retain the brushes in a detachable manner, and so operate them as to reach all parts of the, can.

-. With these and other objects in view, my invention consists in certain constructions and combination of parts as will hereinafter be fully described and claimed in the speciiication, and illustrated in the accompanying drawings which form a part of this application, and in which like figures of reference refer to corresponding parts in all of the views; but-it is fully understood that while I have here described my deviceas shown,

I do not confine myself to the exact design,

as slight changes may be made in the construction and arrangement of the several parts without departing from the spirit of the invention.

' In the drawings Figure l, is a front elevation of the device showing the same in an operating position, and a can in place shown in section.

3 Fig. 2, is a similar view of the same in a closed position ready to enter the can.'

Fig. 3, is a side elevation of Fig. 2, with the brushes removed. r

Fig. 4, is an enlarged sectional detailview of a portion of the operating means.

Figs. 5 and 6 are vertical sections, the section.in Fig. 6 being taken at an angle to that shown in Fig. v

. Referring to the drawings 1, is the vertical combined water and steam pipe which is open at the '11 per end to suppl steam and and which is connected at the bottom by the coupling to the piping'system of the machine.

Mounted on the pipe 1, is a tubularishaft 2, which has a vertical'sliding adjustment, whlch will hereinafter be fully described.

Embracing the shaft 2, is a second hollow shaft 3, which isrotated by a bevel gear 4, secured thereon, near the lower end thereof, and adjacent to the frame 5, of the machine and operated by a bevel gear '6, on a horizontal drive shaft '7, mounted in the frame 5, of the machine. I

-Mounted upon the lowerend of the shaft 2, and secured thereto by the pins 8, is a flanged sleeve 9, upon which is a cushion spring 10, having the washers 11, above and below and limiting the action of said spring 10; while mounted on the vertical rods 12,

in the frame 5, is a yoke 13, embracing the sleeve 9, and being against the upper'washer 11, and operated by a lever23. The operation of lever 23 causes the movement of yoke 13, and the sleeve 9 rigidly carried by Above this is'mounted the lower. set of a brushes for washing the mouth of the can, WlllCl'l comprises a spider 15, secured in a rigid manner by the in. 16, to the shaft 3,

and a second spider 1 ,slidably mounted on the shaft 3, and prevented from revolving thereon by a feather 18, secured in said shaft 3, and engaging a keyway in said spider.

Hinged to said spider 17, are the lower hinged to the brushholders 20, whichhave their uppernends hinged to thespider 15, in .such a manner that whenthe shaft .3,vis revolved, the brushes will be thrown by cenends of links 19, having their upper ends I trifugal force into the position shown in The upper set of brushes for washingthe inside of the can 21, are mounted as follows A collar 22, above the upper the shaft 3 is movable vertically, and a member 23, is slidably mounted on the shaft 3, in the following manner, viz., referring touthe. de tail shown in Fig. 4,.this member 23,'ispro- Ivided with. the screws 24 threaded through the side thereof, and having their ends extending through slots 25, in the walls of. the shaft 3, and into the holes 26, in the walls of the shaft 2. I

By this construction the shafts 2, and 3, and the member 23, all revolve upon the pipe 1, and the member 23, and shaft 2, are locked together and yet vertically movable upon the shaft 3.

The upper end of the member 23, is provided with cars 27, within which are pivoted the lower ends of the brush block links 28, and 29. The link 28, is pivoted to the brush block 30, while the link 29, is pivoted to the brush block 31, near the lower end thereof.

The collar 22, is also provided with similar ears 32, to which are pivoted one end of the links 33, and 34. The outer end of the link 33, is pivoted to one end of the brush block 35, and the outer end ofthe link. 34, is pivoted to a short link 36, connecting with. the upper end of the brush block 31.

Below the member 23, is a collar 37, which is slidably mounted on the shaft 3. Upon the stud screw 38, are pivoted the lower ends of the adjustable arms 39; while to the upper ends of said arms 39, are pivoted the lower ends of a pair of cross arms 40, which are pivoted at their point of intersection 41, to the collar 22, and their upper ends are connected by links 42.

There is also a link 43, connecting the pivot point of one link 42, and one arm 40, with the top of the brush block 30, and a link 45, connecting the top of the brush block 30, with the bottom of the brush block 35.

The can is inverted and placed in the position shown in the drawings with the brushes in collapsed position therein. In starting the washing operation the yoke 13 is moved to its upper position by means of lever 23 raising shaft 2 and collar 23 to a limited extent, and rotary movement is imparted to shaft 2 by the driving means. The centrifugal force will expand the upper brushes and permit them to move upwardly, in view of the mounting means described. The lower set of brushes is opened by centrifugal action, the spider 17 sliding on the shaft 3 against the action of spring 50.

When the bottom of the inverted can and the adjacent portions of the walls have been cleaned, the remaining portions of these walls are then operated upon.

The initial downward movement of yoke 13 by lever 23" will pull shaft 2 downwardly and carry collar 23 downwardly and thereby move collar 37 downwardlyand permit coll'ar 22 to move down, in view of the link conneotion 39 with collar 37 and link connection'4O with collar 22, the brushes remaining in expand d position but being lowered.

On the further downward movement of the yoke 13 the collar 22 engages the upper end of the shaft 3 and collar 23 continues to move down and closes the brushes by means of the links 39 and 40.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent is 1. In a device of the class described, a tubular shaft for conveying cleaning fluid, a slidable shaft mounted thereon, a rotatable shaft carried by the slidable shaft, 2. set of collapsible brushes driven by the rotatable shaft and positioned to engage the neck portion of a can, a spring retaining said brushes normally in collapsed position, a collar slidable on the rotatable shaft, a collar slidable on the shaft first named, an additional collar slidable on the rotatable shaft and movable therewith, a second series of brushes and link connections between said brushes and the first and second named. collars, and link connections between the link connections first named and the additional collar for collapsing the brushes.

2. In a device of the class described, a tubular shaft for conveying cleaning fluid, a slidable shaft mounted thereon, a rotatable shaft carried by the slidable shaft, a set of collapsible brushes driven by the rotatable shaft and positioned to engage the neck portion of a can, means for retaining said brushes in collapsed position and permitting the brushes to be thrown outwardly by centrifugal action, and a set of brushes above the brushes first named for engaging the inner walls of the can, and me'ansfor mounting the brushes last named and giv+ ing an initial upward movement thereto by the movement of the slidable shaft, said mounting means permitting of the expansion of the brushes last named by centrif ugal action.

3. In a device of the class described, a tubular shaft for conveying cleaning fluid, a slidable shaft mounted thereon, a rotatable shaft carried by the slidable shaft, a collar slidable on the rotatable shaft, a collar slidable on the shaft first named, an additional collar slidable on the rotatable shaft and movable therewith, a series of brushes and link connections between said brushes and the first and second named collars, and link connections between the link connections first named and additional collar, for collapsing the brushes.

4. In a device of the class described, a tubular shaft for conveying cleaning fluid, a plurality of concentric shafts carried by the shaft first named, one of said concentric shafts being slidable and the other of said shafts being rotatable, driving means for longitudinal movement of the slidable shaft,

said brushes being thrown outwardly by centrifugal action and moved upward by the mechanical action of the mounting means incident to the centrifugal action.

5. In a device of the class described, a plurality of concentric shafts one of which conveys a cleaning fluid, one of which is slidable longitudinally and one of which is rotatable, means for driving the rotatable shaft, a set of brushes including a plurality of oppositely located brush elements, and an additional brush element mounted above those first named, said rotatable shaft imparting rotary movement to all of the brushes and the mounting means permitting 15 position at an angle with the brushes first 20 named.
